Ua ib yam khoom siv refractory zoo heev,cov cib mullite sib duatau txais kev nyiam dav hauv kev lag luam thoob ntiaj teb rau lawv cov rwb thaiv tsev zoo heev, tiv taus kub siab, thiab cov khoom sib dua. Tsim los ua kom tau raws li cov kev cai nruj ntawm cov khoom siv kub siab, cov cib no tsis yog tsuas yog txo kev siv hluav taws xob xwb tab sis kuj ua rau lub neej ua haujlwm ntawm cov cub tawg kev lag luam ntev dua, ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau cov tuam txhab uas nrhiav kev ua haujlwm zoo thiab kev txhim kho ruaj khov.
Cov lus qhia ntawm cov cib mullite sib dua yog tus qauv thiab hloov kho tau kom haum rau ntau yam xwm txheej kev lag luam. Cov qauv tseem ceeb suav nrog JM23, JM25, JM26, JM27, JM28, JM30, thiab JM32, nrog cov ntsiab lus alumina txij li 40% txog 77% thiab cov ntsiab lus hlau oxide tsis pub ntau tshaj 1.0% (qis mus rau 0.5% rau cov qauv purity siab). Lawv qhov ceev yog 0.55g / cm³ txog 1.35g / cm³, thiab lub zog tsoo txias yog 1.0MPa txog 3.5MPa, ua kom muaj kev ua haujlwm ruaj khov nyob rau hauv ntau yam kev mob thauj khoom. Qhov kub ntawm kev faib tawm yog 1260 ℃ txog 1760 ℃, qhov kub ntawm kev thauj khoom mos yog 1080 ℃ txog 1570 ℃, thiab qhov hloov pauv mus tas li tom qab cua sov kub yog -1.5% txog 0.5%. Qhov loj me yog 230x114x65mm, thiab cov qhov ntau thiab tsawg raws li cov neeg siv khoom xav tau rau cov masonry seamless.
Qhov thermal conductivity ntawm cov cib mullite sib dua yog qis li 0.18W / (m · K) ntawm 200 ℃, uas tuaj yeem txo qhov poob cua sov thiab txhim kho kev siv hluav taws xob - qhov tseem ceeb hauv kev tsim khoom lag luam. Ua los ntawm cov alumina thiab silica uas muaj kev ntshiab siab, cov cib no tsim cov qauv crystalline mullite ruaj khov, muaj cov iav theem me me, cristobalite, lossis corundum, uas ua rau lawv cov thermal shock tsis kam thiab tshuaj tiv thaiv corrosion zoo heev. Lawv tuaj yeem sib cuag ncaj qha nrog cov nplaim taws, tshem tawm qhov xav tau cov txheej rwb thaiv tsev ntxiv thiab ua kom yooj yim rau cov txheej txheem masonry.
Cov cib mullite sib dua muaj ntau yam kev siv, suav nrog metallurgy, ceramics, iav, petrochemical thiab lwm yam kev lag luam. Hauv kev lag luam metallurgical, lawv siv rau hauv cov kab ntawm cov cub tawg kub, lub cev cub tawg thiab hauv qab, thiab cov cua sov hluav taws xob ua hlau, uas tsis tsuas yog tuaj yeem tswj qhov kub thiab txias ruaj khov tab sis kuj txo kev siv hluav taws xob. Hauv kev lag luam ceramic, lawv yog cov ntaub ntawv zoo tshaj plaws rau cov kilns roller, shuttle kilns, thiab drawer kilns, ua rau muaj cua sov thiab txias sai thiab txhim kho kev tsim khoom.
Hauv kev lag luam iav, lawv siv rau cov khoom siv rov ua dua tshiab ntawm cov iav yaj thiab cov channel pub, uas tuaj yeem tiv taus qhov kub siab thiab kev puas tsuaj ntawm cov tshuaj lom neeg kom ntseeg tau tias cov khoom zoo. Hauv kev lag luam petrochemical, lawv siv rau hauv cov kab ntawm cov roj av tawg, cov khoom siv hloov pauv ammonia, thiab cov roj seem gasification furnaces, uas tuaj yeem tiv taus qhov chaw ua haujlwm hnyav. Tsis tas li ntawd, lawv siv dav hauv ntau yam hluav taws xob, cov hlawv hluav taws, thiab cov khoom siv kub siab, muab kev rwb thaiv tsev thermal txhim khu kev qha thiab kev txhawb nqa cov qauv.
Piv nrog cov cib refractory ib txwm muaj, cov cib mullite sib dua muaj qhov zoo pom tseeb: qhov ceev qis tuaj yeem txo qhov hnyav ntawm lub cub tawg thiab cov qauv, qhov thermal conductivity qis tuaj yeem txuag tau 15% -20% ntawm roj, thiab qhov huv siab ua kom muaj kev ua haujlwm ruaj khov hauv cov huab cua nyuaj. Txawm hais tias nws yog cov lus qhia tus qauv lossis cov lus qhia tshwj xeeb, lawv tuaj yeem ua tau raws li ntau yam kev xav tau ntawm ntau yam lag luam. Xaiv peb cov cib mullite sib dua zoo los pab koj txo cov nqi khiav lag luam, txhim kho kev ua haujlwm ntau lawm, thiab ua tiav kev txhim kho ntsuab thiab ruaj khov.
